Answer:

Predators are an important part of a healthy ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals. Also, by controlling the size of prey populations, predators help slow down the spread of disease.

Explanation:

your small your small intestines can't absorb either lactose or maltoseyou use different enzymes to digest the two sugars lactase break down lactose why an enzyme called sucrase-isomaltase breaks down maltose because enzyme are so specific with regard to function you can't break down maltose with lactose or vice versa

Lactase breaks down only lactose in food in our body can absorb it not maltose and sucrose as enzymes are specific in nature.

Enzymes are protein which act as a catalysts and speed up the rate of biochemical reactions with out changing the structure of the final product.

Enzymes can control the speed and specificity of the chemical reaction, and  the rate of biochemical reaction often influences enzymes and they can take place at a relatively low temperature; it   lower the activation energy.

The enzyme activity pH specific, that is at a particular pH, each catalyst is most active for example at PH 2 for pepsin, pH 8.5 for trypsin, for example.

Both enzymes have active sites which can activate biochemical reactions. It is soluble in water, dilute glycerol, NaCl, and dilute alcohol.

Answer:

19°

Explanation:

From 10 to 20, there are 4 lines.

Each line stands for 2, and the fourth line between 10 and 20 is 18. The red stops between 18 and 20, so the answer is 19 degrees.

Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".

The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.

Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

Answer:

in the oceans

Explanation:

Over 97 percent of the earth's water is found in the oceans as salt water. Two percent of the earth's water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth's water available to us for our daily water supply needs.

Answer:

1. produces genetic variations.

2. produces resistance to unfavorable conditions.

3. produces disease-free seed plants.

Explanation:

Sexual reproduction causes more genetic variation. More genetic variation results in diverse immune systems and traits that are advantageous to survival. Variation is good because it allows a species to adapt to new environments.

The advantages of sexual reproduction is produces resistance to unfavorable conditions, produces genetic variations and produces disease-free seed plants.

Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes.

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.

Three mechanisms contribute to genetic variation arising from sexual reproduction: independent assortment of chromosomes, crossing over, and random fertilization.

The equation is balanced because the mass and charge are equal on both sides of the reaction equation.

In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.

The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

Answer:

DNA stores that info

Explanation:

In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).

The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.

The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.

The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.

During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.

The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

Answer:

A- Vacuole  

B- Chloroplast  

C- Cell membrane

D- Golgi bodies

E- Smooth and rough endoplasmic reticulum  

F- Cell wall

Explanation:

This is a structure of a plant cell which unlike animal cell has a cell wall as well as plasma membrane. It also contains large vacuoles present in the center of the cell. The green color of the plants is due to the presence of chlorophyll which is present in an organelles called chloroplast.

Organelles which are labelled in the cell are

A:Cell membrane

B:Vacuole

C:Nucleus

D:Cytoplasm

E:Chloroplast

F:Cell wall

The given figure represents a plant cell. So, the correct option is C.

Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.

In the given figure, labelled organelles function are as follows:

Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.

Thus, the given figure represents a plant cell. So, the correct option is C.
